Deploy the e-commerce platform in a single Azure region using Availability Zones for high availability, and implement geo-redundant storage for data backup, ignoring region pairs to reduce complexity and cost.

Utilize Availability Zones within a primary Azure region for high availability and pair this region with another in the same geography for fault tolerance, ensuring compliance with data sovereignty laws and minimizing latency.

Distribute the e-commerce platform across multiple Azure regions globally without using Availability Zones, to ensure fault tolerance and compliance with data sovereignty laws, despite higher costs and potential latency issues.

Focus on deploying redundant instances of each resource within a single Availability Zone in one Azure region, to simplify the architecture and reduce costs, while relying on Azure's built-in resiliency features.

Combine the use of Availability Zones within a primary region for high availability and leverage Azure region pairs for fault tolerance, ensuring data residency compliance and optimizing for cost and performance.
